Definitions

  • the vehicle battery device further has a ground connection. This is connected via a first switch to the first accumulator, in particular to a negative terminal of the first accumulator.
  • the ground terminal is connected via a second switch to the second accumulator, in particular with a negative pole of the second accumulator.
  • control unit can be drivingly connected to a rechargeable battery or to both rechargeable batteries, in particular to a battery management unit of the rechargeable battery, which is set up, for example, to control charge equalization between cells of the respective rechargeable battery.
  • the control unit is set up to open the connected switch upon detection of a cell defect within one of the accumulators. If the first accumulator is detected as defective, the first switch is opened. If the second accumulator is detected as defective, the second switch is opened.
  • the control unit can have a control output which is connected to a respective control input of the control unit
  • the positive pole of the first accumulator 10a, b corresponds to the positive pole of the first cell ⁇ stacking section 10a of the first accumulator.
  • a second positive terminal 24 of the illustrated device is connected to the positive pole of the second accumulator 20 and the intermediate tap 12 (and thus point Bl).
  • the nominal voltage of the first accumulator 10a, b is 48 volts; the rated voltage of the cell stack section 10b is 12 volts while the second secondary battery 12 has a nominal voltage of 12 volts.
  • Charge compensation can take place via the point B1 between the second accumulator 20 and the (second cell stack section of) the first accumulator (s).

Abstract

L'invention concerne un dispositif de batterie de véhicule pourvu de : un premier accumulateur (10a, b) qui comprend un point de prise intermédiaire (12) ; un second accumulateur (20) qui comprend un pôle plus ; ainsi qu'un premier et un second branchement positif (14, 24). Le pôle plus du second accumulateur est relié au point de prise intermédiaire (12) du premier accumulateur. Le second accumulateur (20) présente une tension nominale qui est inférieure à la tension nominale du premier accumulateur (10). Le premier branchement positif (14) est relié à un pôle plus du premier accumulateur (10a, b). Le second branchement (24) est relié au pôle plus du second accumulateur (20). Un branchement de masse (30) du dispositif de batterie de véhicule est relié par l'intermédiaire d'un premier commutateur (SW1) à un pôle moins du premier accumulateur (10a, 10b). Le branchement de masse est en outre relié par le biais d'un second commutateur (SW2) à un pôle moins du second accumulateur (20).
